M365 Changelog: (Updated) Shared Device Mode for Outlook Mobile on Android

MC496631 – Updated January 31, 2023: Microsoft has updated the rollout timeline below. Thank you for your patience.

Shared device mode is a feature of Azure Active Directory that allows you to use applications that support frontline workers and enable shared device mode on the devices deployed to them

Your frontline workers can preview Outlook on their shared Android devices until full rollout begins. Enabling frontline worker workflows includes challenges not usually presented by typical information workers. Such challenges can include high turnover rate and less familiarity with an organization’s core productivity tools. To empower their frontline workers, organizations are adopting different strategies. Some are adopting a bring-your-own-device (BYOD) strategy in which their employees use business apps on their personal phone, while others provide their employees with shared devices like iPads or Android tablets.

This message is associated with Microsoft 365 Roadmap ID 107506

When this will happen:

Public Preview will be rolling out in mid-February (previously mid-January 2023).

General Availability will be rolling out in mid-June 2023 and is expected to be complete by mid-July 2023.

Because mobile devices running iOS or Android were designed for single users, most applications optimize their experience for use by a single user. Part of this optimized experience means enabling single sign-on across applications and keeping users signed in on their device. When a user removes their account from an application, the app typically doesn’t consider it a security-related event. Many apps even keep a user’s credentials around for quick sign-in. 

To allow an organization’s employees to use its apps across a pool of devices shared by those employees, developers need to enable the opposite experience. Azure Active Directory will enable the following scenarios with the shared device mode features:

  • Employees will have the ability to pick a device from the pool and “make it theirs” for the duration of their shift.
  • At the end of their shift, employees can sign out globally on the device, with all of their personal and company information removed so they can return it to the device pool.
  • If an employee forgets to sign out, the device will automatically be signed out at the end of their shift and/or after a period of inactivity. 

What you need to do to prepare:

You can use the Microsoft Authentication Library (MSAL) and Microsoft Authenticator app to enable a device state called shared device mode. When a device is in shared device mode, Microsoft provides your application with information to allow it to modify its behavior based on the state of the user on the device, protecting user data.
